with regards to off-site data, - i think it very much depends on how you split the data. I can take all age range data for 6'0 height and get 0.48 vs 0.52 splits for 6'0 vs 6'5 - so i think it very much depends on this split (and hence where my 6'0 6'5 comment came from). I split it several other ways and got different results again. Stats lie 101% of the time.
Im always VERY skeptical of the offsite data as well and when i first saw the passing speed analysis i was like nahhhhhhhh thats crapola, seems really stupid.
But I can only base off my own personal experiences in training 6'1 PG in passing for a few seasons, vs my now 7'2 and 7'5 guys in passing. and from experiencing it first hand, i do find it to be true with regards to height and passing.
You both make some good points. And indeed Handling has more effect on Passing than other skills according to the off-site data blog. But I think I remember a news post where they said they would link the other skills more as well.
Anyway, as I said I might very well be wrong. So I was thinking of taking another look at the data. You are right that it can be split in many different ways so I hope you believe me that in my last post I only split it 1 way and am not fishing for good results. Als this time the data I gathered was only from 1 split and feel free to change the parameters and look up the data for those.
But I was still wondering. If height is actually the main effect we should see a pretty similar effect of it across the ages. In other words, tall 18 yr olds should have the same height advantage as 24 yr old. But if the height advantage is much much bigger for older players something else than height might be the factor (OR there might be a second factor besides height of course, like the one Hrudey proposes f.e.).
I checked data for every age from 18 to 25 for 2 groups, 5'9-6'3 and 6'7-7'6 (randomly picked...I swear).
18/19/20/21/22/23/24/25 yr old
5'9-6'3
.64/.58/.56/.51/.45/.4/.33/.27 (skill increase for respective ages)
6'7-7'6
.61/.6/.56/.52/.49/.51/.44/.38 (skill increase for respective ages)
Differences:
-3/+2/0/+1/+4/+11/+11/+11
(if we plot it this is definitely not horizontal)
It does not discount your personal experience, which is very valuable as well since you actually know all their variables. But this makes me wonder if the graph on the offsite wouldn't have shown an effect for height if only 18-22 yr olds would have been used. And I wonder why that is if height actually has a significant main effect.
